To blanch the green beans, add a few cups of water to a pot or a deep pan with a strainer or use a steamer strainer.
Add the green beans and close with a lid. Bring to a medium heat, the water will bubble and begin to cook the green beans. Keep the green beans blanching for approximately 5-7 minutes or until just fork tender, then turn off the heat.
Strain the green beans and add back to the deep pan or if you've blanched in a pot, strain and add to a skillet or frying pan with olive oil on medium heat.
On a medium heat, let the green beans sauté in the olive oil until they start to char and get softer. Cooking the green beans will take approximately 5 minutes. The green beans should be fork tender, but have a slight snap or crunch.
To the green beans, add in the garlic, salt, and pepper. Continue to cook until the garlic becomes slightly translucent and fragrant, approximately 3-4 minutes. Turn off the heat, and serve.
